This is a collection of 42 essays about the economics and management of information technology markets. The first part of the book focuses on events, notable birth dates and longstanding trends. The unifying theme revolves around the role of human economic behavior in the face of uncertainty and confusion. The contributors' intent is to explain, educate and entertain -- to go beyond the obvious. The next part contains writing about the Internet. It discusses the development of the online commercial world, and analyzes the macroeconomic side of the investment boom and bust related to Internet activities. It also focuses on the measurement of economic activity in the digital economy. In addition, the book deals with how computers get used in organizations and discusses the Microsoft antitrust case. Finally, there are two long essays about economic constraints on strategic behavior in markets where standards and platforms matter.
